Have been following this tread with interest..

Had a go myself and have fitted the silicone pipe, pipercross panel filter, plumbers bits and removed the HHR today.



Sounds better to me already!!

Should be even better when I get the 1" bypass on the exhausts done in 1 & 1/2 weeks time!

GT4, thanks for the excellent guide worship

It turns out my tiptronic does have the extra 'little breather pipe', i will buy the little breather filter so i can do the hhr mod!

I tried it on my tip with the extra breather pipe. As a trial, I just blanked off the HHR pipe at the airbox lid.

I have now put the car back to standard as I felt that it was affecting the tip gearbox changes at part throttle. This may be due to strange pressure fluctuations caused by the blanked off pipe, but whatever the cause I have reverted to standard (and the nose gain was not that noticeable with the PSE mod).

As the breather pipe is purely to allow vaporised transmission fluids (lubricants/hydrocarbons) to be burnt off in the engine, I can't really imagine this making any difference (particulary as you aren't even blocking off the breather pipe).

It won't make circa £2.5k of difference (OPC PSE) or even £250 difference (average Oettle price) as it is a £2.52 mod!

Well I got the designtek kit today, took the air box out, took the resonator out, put the alloy bung in the hole, I dropped straight through!

Put the resonator back in and fitted the bung.

Put the new silicone pipe on and went for a drive.

Didn't sound any different!

Sad

TURN YOUR HEARING-AID DOWN, YOUR'RE GETTING FEEDBACK FROM CLASSIC FM.

Now go out and spend £2.52 on some plumbing bits'n'bobs, you tight bar steward.

PS - I've been waiting in, 'cos the letterbox ain't big enough, and still no sign of that boat?

No.

Is it a part work? Over how many weeks?

Anyway, I'm completely upfront, it's a GT4!

Very embarrassing last year at PCGB Concours, got directed to the "GT3" arena Embarassed

Had an argument just to get out and move to the cooking section.

It's not like I even had the (previous) owners GT3 badge on still.

That only lasted two months of my ownership, until I could bear the questions (or jibes) no more and I flossed the damn thing off and it went to the detailers to have the badge "shadow" removed.

Paul, brilliant post, which I have read with interest all the way from page 1.

However, could I clarify then that in order to get slightly better throttle response I need to add the CAI pipe and superior filter, plus need to remove the HHR box and bung it, or can I get away with a kit that includes all excepting the HHR box removal?

I specifically ask with regards to the HHR box as my car is already bloody loud, and I'm not sure I want to replace the windows in my street when I fire her up after HHR mod..

Also I am looking at the Eurocup kit that comes with the filter as well as pipe etc but it seems (from reading this thread) that there are cheaper options to this one which is about 186 quid. If this is so which ones - Evoms, Deisgn 911?

With thanks,

Henry

Standard CAI mod is just the tube and ideally a performance filter.

The HHR mod is just an add on (or perhaps add off Question ).

You can do the former without the latter.

The CAI mods come with an HHR bung just for cosmetics (and to keep spiders and rainwater out of your HHR).

Cheers, TX.

You only need the plumbing bits if you are taking the HHR box out as well.

on the 997s I used just a 40mm PP Push-Fit Waste Access Plug Black, 99p perfect fit.
simply glue the res down, then drop the cap above it, its a perfect fit then the lip sits on the top and you can glue it if you want, then drop the filter pipe on top to make it hidden.

second gear to 4.3 revs sounds like a jet fighter and that noise lasts right through to 6.5, ear poppers.

black also, I know its hidden but better black Smile

That is presumably into the HHR neck? (in which case it is the infamous "orange cap" mod - google is your friend)

Did mine this morning. Surprised by the amount of crap in the air box:




Thanks to GT4 once again for the write up. Thumb

Surprised

Who services your car?

I Hoover mine once a year and the OPC do likewise (plus I don't drive it between 11/11 and 1/3), but I have never seen anything like that.

AddSpeed - Horsham, West Sussex.

Ive only had it long enough for 1 minor service -

- Am I right in thinking the air filter is only changed on majors?
- Would you expect them to hoover it out during a minor service?
